Diamond Saw Blades for Granite Cutting

Yes, diamond blades are specifically engineered to cut granite and other hard natural stone. The diamond segments abrade through the dense material rather than cutting like a traditional blade, and most granite-rated blades support wet cutting to control heat and dust during the process.

Using a wet-cutting diamond blade on a table, masonry, or tile saw is typically the easiest and most controlled method for cutting granite slabs or tiles, since water cooling reduces dust, prevents overheating, and helps achieve clean, chip-free edges.

For countertop fabrication, 14-inch to 20-inch segmented blades are common on walk-behind or table saws for cutting slabs, while 4-inch to 10-inch turbo or continuous rim blades are better suited for detail work, edge finishing, and smaller cuts.

Many diamond blades are compatible with both granite and marble, as well as other natural stone and tile materials. Check the product's compatible materials specification to confirm suitability, since bond hardness may be optimized differently for softer versus harder stone.

Some blades are wet-only, while others support both wet and dry cutting. Wet cutting is generally recommended for granite because it reduces heat buildup, controls silica dust, and extends blade life, though certain U-slot or slanted gullet designs are built for dry use as well.

Signs include reduced cutting speed, visible segment wear below the recommended undercut protection depth, glazing on the segments, or excessive vibration during cuts. Replacing a worn blade promptly helps maintain cut quality and prevents damage to the saw or workpiece.
